Cloak is a new app that bills itself as "incognito mode for real life." It uses the location data from your Foursquare and Instagram to chart out on a map where all your friends and acquaintances are lurking. Your ex just posted a photo to Instagram at 58th St.? ALERT ALERT! STAY AWAY!
It's like a reverse Foursquare: Instead of knowing where your friends are in case you want to join them, you can monitor where they are to actively avoid bumping into them. It's a genius concept, even if it does seem to assume that you're constantly running into old flames, familiar faces, and terrible humans on the street.
Because people don't stay in the same place forever, their icons will start to fade four hours after checking in on Foursquare or posting an Instagram pic tagged with a location.

The app is made by Chris Baker, who also made the baby photo blocker Un.baby.me for Facebook, Troll the NSA, and an assortment of other prankish sites or apps.
Baker used to work in the advertising department of BuzzFeed, but now apparently spends so much of his time actively avoiding his former coworkers that he had to make an app for it.
